Architectural Shingles
If you have a mid-tier architectural shingle with an expected lifespan of 22 years:
Initial Application:
Applied at year 10 (when shingles often start showing signs of oil loss). This adds about 6 years. New Total Expected Life: 22 years + 6 years = 28 years
Second Application:
Applied at year 16 (6 years later). This adds another 6 years. New Total Expected Life: 28 years + 6 years = 34 years
By rejuvenating the roof at the specified interval, you could extend its serviceable life by roughly 12 years (or more) for a total of up to 35+ years before a full replacement becomes necessary.
Crucial Caveat: Rejuvenation is only effective if the roof is still structurally sound and has not yet experienced severe granule loss (typically less than 20% loss), extensive cracking, or significant water damage/leaks. It is a preventative maintenance solution, not a repair for a failing roof system.
